VRZ 1. is a track bike frame with 3d printed Stainless steal lugs glued together with carbon fiber tubes.
The VRZ 2 is the same set up with 3d printed Titanium Lugs and carbon belt drive... so its 4,9 kg
this method allows to build custom frames in a short period of time.
you could change the geometry to what ever you like, then the lugs gets generated by a software.
now we just need to print the parts finish them and glue the frame together.
